Technical Data Sheet

LOCTITE® 5900® April-2006

Typical applications include stamped sheet metal covers (timing covers and oil sumps) where good oil resistance and the ability to withstand high t-movement is required. It withstands on line, low pressure tests carried out before product begins to cure. The thixotropic nature of LOCTITE® 5900® reduces the migration of liquid product after application to the substrate.

Depth of Cure The depth of cure depends on temperature and humidity. Depth of cure was measured on strip pulled from a ramped PTFE mold (maximum depth 10 mm). The graph below shows the increase in depth of cure with time at 23±2 °C / 50±5 % RH. 10

Directions for use 1. For best performance bond surfaces should be clean and free from grease. 2. Moisture curing begins immediately after the product is exposed to the atmosphere, therefore parts to be assembled should be mated within a few minutes after the product is dispensed. 3. The bond should be allowed to cure (e.g. seven days), before subjecting to heavy service loads. 4. Excess material can be easily wiped away with non-polar solvents.
